If his team goes in a different direction in his area of responsibility, he's fails to lead as the lead developer. Verbally kicking players while they're down and hurting with "to the ground baby!" is obnoxious. He was also indecisive; one moment he wanted to drastically nerf mana regen for dps to resources matter then wanted dps not to be throttled in such a manner. Talent trees were constantly changed, and homogenizing classes cause that's his vision of the class(es). Every class has at least one dot and small slow heals are fun.... He tells the crowd that fun is not hitting for big numbers, wtf???? I don't need a self centered marine biologist to tell me what fun is.
Woot he's gone! The new guy might not fix WoW but will be great if he doesn't wreak it further.
